An understanding of statistical principles and methods is essential for any scientist but is particularly important for those in the life sciences. The field biologist faces very particular problems and challenges with statistics as "real life" situations such as collecting insects with a sweep net or counting seagulls on a cliff face can hardly be expected to be as reliable or controllable as a laboratory-based experiment. Acknowledging the peculiarities of field-based data and its interpretation, Practical Statistics for Field Biology introduces readers to the principles and methods of statistical analysis allowing them to understand research reports in journals, decide on the most appropriate statistical tests for their own problems and finally to analyse and present their findings. To enhance the usefulness of this book, the new edition incorporates the more advanced method of multivariate analysis, introducing the nature of multivariate problems and describing the techniques of principal components analysis, cluster analysis and discriminant analysis which are all applied to biological examples. An appendix detailing the statistical computing packages available has also been included. Practical Statistics for Field biology will be of interest to undergraduates studying ecology, biology, and earth and environmental sciences. In addition, it will be useful for postgraduates who are not familiar with the application of multivariate techniques and practising field biologists working in these areas.Review of the First Edition"In summary, Practical Statistics for Field Biology is an excellent introductory text for first and second year undergraduate courses in biology." Trends in Ecology & EvolutionWhat the lecturers said about the First Edition: "An excellent introductory guide to statistics." "Applicable examples in an understandable text." Booknews An introduction to gathering, processing, presenting, and analyzing biological data for readers who have no previous experience with statistics. Unlike most such texts, which are oriented towards laboratory work, it specifically addresses the problems encountered by biologists working in the field, such as non-standard data and the concern with handling count data. Gives the reader a feel for statistics rather than description of a large number of techniques. The exercises and examples can be worked with only a calculator. Annotation c.
